BMW’s M Performance group builds cars like the not-for-U.S.-consumption M550d xDrive sedan, but it also designs and builds components to increase the performance of existing BMW models. The group focuses on four main categories, including aerodynamics, drivetrain, cockpit and chassis.

It’s ironic that M Performance was founded in reaction to the success of aftermarket BMW tuners and parts suppliers, and it’s clear to us that the group has some impressive resources at its disposal. While most aftermarket tuners test parts in competition, we’re not sure how many have the resources to wind-tunnel test aero kits on a rolling platform, which is just one reason to look at BMW’s offerings.

We’d love to see the M Performance group’s M135 hatchback (as seen on track in the video) on these shores, as it could be the ultimate blend of performance and practicality. BMW hasn’t confirmed the rear-drive hot hatch for the U.S., but they haven’t given a flat denial yet, either. We’ve got our fingers crossed.
